The Emirates Stadium is a setting subject to extreme cheer at present, an inevitable outcome of the news that Alexis Sanchez has signed from Barcelona in a £35 million move.

The forward was superb during Chile's run to the World Cup's round of 16 this summer, and upon sealing his switch to North London, told Sky Sports: "I'm so happy to be joining Arsenal - a club with a great manager, a fantastic squad of players, huge support around the world and a great stadium in London."

For Arsenal fans, it's a sensation that doesn't come around all too often. Not only did Sanchez's purchase require a sum of money that isn't regularly splashed by the club's owners, renowned for being stringent in their spending, but it's early business too.
